Amazing motherboard built very well Fast delivery arrived in perfect condition

Item was well received with fast shipping. Maybe there was a slight dent on the outer box itself while checking but it doesn’t damage the motherboard. Overall experience was satisfied. Will purchase again if needed in future.

So as long as you are a advanced PC cooling enthusiast, this product is amazing. I’ve been able to overclock my seventh GEN to 5.2 GHz and able to keep it up there very stable.

I have had nothing but issues with this board. 1.) Parts supplied in box don't match installation instructions. Instructions comment that there are two types of isolation stickers in the box (clear and black that need to be used in two different spots for different hole sizes on the water block mounting, but only supplied with black smaller size.These should be different diameters for the different mounting holes. Note that I had returned the first board given mounting issues from comment 2, and the second board had the same incorrect isolation stickers. I assumed that after two boards with the same issue of only including the smaller black isolation stickers that this was a change in the supplied parts as the smaller black stickers will still work. But given sizing i don't believe this to be totally accurate. 2.) Installation instructions of the back plate tell you to install it 180 degrees off from proper mounting orientation. I assumed that the Asus installation manual was correct and that the latch screw that extends on the back of the board was too long from the factory. After returning the first board i realized that if rotated 180 different from the manual the back mounting plate would clear this screw. (i feel stupid on my end for this one but i was following the manual) 3.)When i received the replacement board the small internal circuit board that is in the water block was broken at the mounting tab. This was visible as the back side of the water block is clear in this area. Side comment on the water block and wires, for a ~$600 board the wires and sleeves on the water block feel and look really really cheap. 4.) After replacing everything, installing and running, water flow meter inside would rattle some times with water flow. Not loud mind you but noticeable even over a water pump at full speed. 5.) When running, after booting into OS board would post Q-code 6F (System Agent DXE initialization) This happened in base non overclocked and auto overclock and manual overclock). Note that the board is already in OS and running fine, no crashes, no instability. But error code will not go away. Tried flashing the Bios, tried new RAM, tried different power supply. Contacted Asus about this and they comment that i should return it.

This board is amazing. The software Ai Suite is horrid. Do all fan changes in the BIOS(trust me) M.2 setup was super easy. Waterblock install was a bit hard. flipping the board over while trying to keep it lined up and not have the heatpads move was a good 15 min chore. Cables become a bit of a mess with CPU and waterblock ports being next to each other. Keep steady temps, even hitting 19C on some nights. using 2 slim 120mm rads. All in all. this board is amazing.And im not done at all. this board will last me at least 7 more years.

Perhaps I didn't do enough research, but I failed to realize that this particular motherboard must be attached to a DIY water-cooling system in your rig. It cannot work without internal water-cooling with additional pipes and water pump and all the necessary bits. So right now, this unit is useless to me until I can purchase all the extra water cooling items I need to connect to this motherboard. The unit itself is very good so I give myself only 3 stars for not doing enough research on the product but I also place some blame on ASUS for not advertising that in BOLD CAPITALS in the first place.
